Use | gives yellow light red, and C.I. Pigment Red 2 compared to a clear yellow light, light fastness slightly lower, and C.I. Pigment Red 53:1 is slightly blue compared with color light, light resistance is about 1 grade higher. Mainly used in fabric printing and ink coloring, especially NC-type ink, alkali resistance, soap is better; Can also be used for air self-drying paint, latex paint and other coloring. There are 34 types of products put on the market. |
